The Acid Flashback Myth

There's a lot of hysteria surrounding LSD. People have died on LSD. Despite the millions of acid trips that people have taken it's never been conclusively shown that LSD led to the death of a human being. The minimum dose is a quarter microgram which is um like 25,000ths of a gram I believe. Some people have taken milligrams of this stuff. Accidentally there was a group of people in 1975 at a party and they thought they were snorting cocaine but it turned out they were snort powdered LSD.
